08421 Working Group: Uncertainty and Trust

Abstract

This report summarizes the findings of a working group on "Uncertainty and
Trust" which met during Dagstuhl Seminar 08421 "Uncertainty Management
in Information Systems". All participants of the working group are co-authors
of this report. The aim of the working group was to analyse the relationship
between trust and uncertainty in distributed reputation systems. We started by
identifying sources and types of uncertainty in this context and investigated their relation to trust. After that we compiled a list of desirable properties of trust representations and finally determined open research challenges in the area.
